Changing the ramp-up and ramp-down times in operation
The ramping up and down time of the ramp-function generator can be changed during
operation. The scaling value can come, e.g. from the fieldbus.
Preconditions
• You have commissioned the communication between the converter and the control system.
• Free telegram 999 has been set in the converter and in your higher-level control system.
• The control sends the scaling value to the converter in PZD 3.
Procedure
1. Set p1138 = 2050[2].
This means that you have interconnected the scaling factor for the ramp-up time with PZD
receive word 3.
2. Set p1139 = 2050[2].
This means that you have interconnected the scaling factor for the ramp-down time with
PZD receive word 3.
The converter receives the value for scaling the ramp-up and ramp-down times via PZD
receive word 3.

Setting
Sets the highest possible speed.
Factory setting: 1500
Sets the ramp-function generator type.
0: Basic ramp-function generator
1: Extended ramp-function generator (factory setting)
The ramp-function generator ramps-up the speed set-
point from standstill (setpoint = 0) up to the maximum
speed (p1082) in this time.
Factory setting: 1
Sets the ramp-down time for the ramp-function generator.
Factory setting: 1
Sets the ramp-down time from the maximum speed
down to zero speed for the OFF3 command.
Factory setting: 0
Setting
Sets the signal source for scaling the ramp-up
time of the ramp-function generator.
Factory setting: 1
Sets the signal source for scaling the ramp-down
time of the ramp-function generator.
Factory setting: 1
Connector output to interconnect PZD (setpoints) with
